We've never had nannies. We've had great grandparents, great support from family, and the kids have been on every set: they've seen me play Gollum, King Kong, Captain Haddock, the lot. They totally get it, and they want to go into the business. Ruby, my daughter, is very keen to become an actress.

We're live in a world that has, in many ways, become desensitized and unable to empathize with other cultures and species. The dangerous part is that we objectify others and have somehow removed ourselves, mentally, from the very planet we inhabit.

What's wonderful about Tolkien and Shakespeare is that they show up your own individual microscope. They're so infinitely vast. You can reinterpret them in so many ways. Each age will have its own resonance with Lord of the Rings.

It's really up to the acting community to be willing to be educated about what performance capture is in order to fully appreciate it as acting. It's not a type of acting, but rather the use of technology to harness an actor's performance and translate it into an ape, another animal, or an avatar of some kind.

It's a different rhythm than most movies. For a lot of the actors, you're 12,000 miles away from home. It becomes a way of life - getting up at five in the morning, shooting every day, day in day out, for 270 days. The new cast playing the dwarves were carrying incredibly heavy weights in their suits, they sat through hours of make-up every day. So it's quite challenging from a stamina point of view.

I'd like to think that we strive in film and theatre to tell great stories, and I believe in the power of storytelling in our culture.

That's what I think is the biggest challenge, is just being still and learning how to just be present in that stillness and not over do it, not over act.
